CONTEXT EUS-guided transmural drainage of pancreatic pseudocyst has been reported using a linear array echoendoscope; however, placement of large 10 French stent was not feasible because of the limited diameter of the working channel. Recently linear array echoendoscopes with large working channel (3.7 to 3.8 mm) and newer accessories for pancreatic cyst puncture have become available; however,...

The rational method is derived as a special case of kinematic wave flow. The definition of runoff coefficient is expanded from the flow-based ratio into volume-based ratio between the volumes under runoff hydrograph and rainfall hyetograph. The new method presented in this paper provides a dimensionless approach to theoretically derive the runoff coefficients for both the conventional two-flow ...

Measurements of saturated hydraulic conductivity (Ks) in the field are costly, time-consuming, and relatively cumbersome, chiefly as hydraulic conductivity exhibits a large spatial variability, so that it becomes difficult to find accurate representative values to correctly predict soil-water flow and design irrigation and drainage systems. Ks was measured in seven different soils in Egypt to e...

This paper presents a new approach for the computation of flow velocity in pipes arranged in parallel based on an analytic development. The estimation of the flow parameters using existing methods requires trial and error procedures. The assessment of flow velocity is of great importance in flow measurement methods and in the design of drainage networks, among others. In drainage network design...

Binder drainage test is widely used to set an upper limit to the design binder content of porous asphalt. However, the presence of high amount of fine particles in the drained binder may affect the accuracy of the test result. This paper presents a study to characterize the composition and particle size distribution of fine particles accumulated in the drained binder. Fine aggregates and filler...

Green cities can solve urban problems without destroying the environment. city planning be implemented through green and design. The purpose of this research is to generate design streets that support realization cities. closely related principles. method used a qualitative with observational data collection. location center Medan City where open space connected city’s main road network. ...

BACKGROUND Tuberculous pericarditis is common in Transkei (Eastern Cape). Two randomized trials showed benefits at two years for prednisolone in patients with constrictive pericarditis, and open drainage plus prednisolone in patients with pericardial effusion. AIM To see whether the advantages of prednisolone and open drainage were maintained up to 10 years. DESIGN Follow-up of randomized, ...

background: historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. the records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. methods: the clinical features, laboratory tes...

iran is ranked fourth for saline-sodic soils in asia following china, india and pakistan. therefore, if coupled with waterlogging, drainage would be an inevitable and indispensable activity agriculture in most irrigated parts of iran. drain installation depth is one of the main economic as well as environmental challenges in design and construction of drainage systems. deep pipe drain installat...
